Already an opening novelty. Robson was clearly surprised by the last move and spent a long time on his reply.
7... d4e4  8. g1e2  8... b8a6  9. b4f8 A pretty move that is well-known. 9... e4g6 Very rare. Arjun is an interesting player for the audience since he is always willing to take great risks in order to play for a win. He surely has a lot of analysis here. Both 10.Qd6 and 10.Nf4 are critical.
